“…Pubescence (having dense trichomes) in other plants has been reported to confer resistance to some insect herbivores. [ 15 16 17 18 19 20 21 ] A literature review indicated that a majority of botanical descriptions of trifoliate orange failed to mention leaf trichomes including a comprehensive review by Swingle and Reece. [ 22 ] We, therefore, decided to investigate trichomes associated with the psyllid-resistant trifoliate orange plants in comparison to five other genotypes regularly colonized by D. citri : lemon ( Citrus jambhiri Lush.…”

Background and Significance:Foliar trichomes (tiny hair-like structures) are part of the plant defense mechanisms that may confer resistance to some herbivore pests. Trifoliate orange, Poncirus trifoliata, is a genotype resistant to infestations by the Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae), vector of the economically important citrus greening (huanglongbing) disease bacterium. We discovered that dense trichomes are associated with young leaves of trifoliate orange plants and hypothesized that these might be responsible for reduced infestation by this psyllid.Materials and Methods:Epifluorescence and stereomicroscopy were used to study the density and structure of trichomes associated with young flush leaves and stems of trifoliate orange and of five other plant genotypes that are highly susceptible to colonization by the psyllid: lemon, grapefruit, sweet orange, curry leaf, and orange jasmine.Results:Simple unicellular trichomes were observed at moderate-to-large densities on young leaves and stems of each genotype except lemon and sweet orange, which had considerably fewer trichomes. Trichomes were generally abundant on young leaves of curry leaf and orange jasmine, two genotypes that are often heavily colonized by the psyllid. Although we did not quantify oviposition rates on these genotypes, we observed that psyllid females deposited eggs on young leaves, buds, and stems regardless of the density of trichomes present, sometimes directly within or close to a dense bed of trichomes.Conclusions:While trichomes were moderately abundant on young leaves of trifoliate orange, our results strongly suggest that these trichomes may play little or no role in reduced colonization by the psyllid on this genotype.

“…Based on the available literature, the duration of the egg to adult period varies between bean genotypes, and there are reports of periods between 16.20 and 41.00 days (Oriani and Lara 2000;Torres et al 2012). Some references reported a large variation in the development period of the whitefly on cowpea genotypes (Cruz et al 2014), cabbage (Villas Bôas et al 1997), cotton (Prado et al 2015), soybean (Cruz and Baldin 2016), tomato (Baldin et al 2005), squash varieties (Baldin and Benduzzi 2010), melon (Baldin et al 2012) and, more recently, peppers, where a duration of 30.25 days was observed (Pantoja et al 2018), similar to the present study.…”

Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis

et al. 2020

The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM) program. The biological development of B. tabaci confined to 17 bean genotypes was evaluated in greenhouse trials to verify the occurrence of antibiosis. Whitefly adults were released on plants of these genotypes to oviposit, afterward the incubation period of eggs, nymphal period, complete development period (egg-adult), and viability of the silverleaf whitefly nymphs were recorded. As main results, genotype CHIP 300 prolonged the developmental period from egg to adult (~10 days) and BRS Estilo, Arcelina 4, IPR Garça, Tybatã, CHIP 300, IPR Eldorado, H96A102-1-1-1-52, SCS-202-Guará and CHIB 06 caused nymphal mortality, suggesting high levels of antibiosis and/or antixenosis. These genotypes may be helpful in common bean breeding programs aimed at developing commercial cultivars resistant to B. tabaci biotype B.

“…Among the strategies of IPM, it is possible to emphasize the method of plants resistant to insects, which has the advantage of causing a little impact on the environment and being easy to use (Smith 2005;Pretty & Bharucha, 2015;Almeida et al 2017). There are reports of the occurrence of plants resistant to B. tabaci in soybean crops (Bray et al 2016;Rodrigues et al 2021), cotton (Prado et al 2016), melon (Baldin et al 2012), squash (Baldin & Beneduzzi 2010), tomato (Firdaus et al 2012) and cucumber (Novaes et al 2020).…”

This study aimed to evaluate the biological development of Bemisia tabaci MEAM1 confined on eleven soybean cultivars under greenhouse conditions and estimate genetic parameters for correlated resistance traits. Twenty individuals of B. tabaci were released in cages and closed in the petioles of the plant leaflets. A completely randomized design was used with eleven treatments and five replicates. The evaluations occurred over 25 days. The insects that emerged from the bioassay were confined to plants of their respective cultivars. This procedure was performed on five generations of the insect to evaluate the ability of the plant to express resistance by generations of the whitefly. It was found that M 8808 and AS 3810 negatively affected the oviposition of B. tabaci. The cultivar BRS 9280 affected the development of the insect. According to the selection index, the cultivars that showed best performance were BRS 9280, AS 3810, M 8808, and BRS 8383. The cultivars BRS 9280, AS 3810, and M 8808 expressed resistance characteristics for five generations when analyzed under the pressure of whiteflies, which are considered sources of resistance to B. tabaci MEAM1 for breeding programs to obtain resistant cultivars.
